' WATER-WHEEL.

Patented Feb. 8,1910.

Application filed July 27, 1908. Serial-No. 445,649.

To all whom it may concern:

Be it known that I, FRED BANGERTER, a citizen of Switzerland, residing in the borough of Brooklyn, county of Kings, city and State of New York, have invented cor-- ta-in new and useful Improvements in later- Wheels, of which the following is a specifi- CtIlIIOII.

This invention aims to provide certain improvements in the construction of water wheels such. as are used in water meters, being rotated by the passage of the water through the meter and against the buckets of the wheel; and is applicable to wheels used in analogous situations.

The improvement is especially in the manner of forming and applying the bnckets or pockets of the wheel, and in the general construction of the wheel.

.The accompanying drawings illustrate an embodiment of the invention.

Figure 1 is a tangential vertical section of a standard water meter. Fig. 2 is a plan, partly in'section, of the water wheel. Fig. 3 is a section through the disk of the Water wheel. Figs. 4 and 5 are respectively a. horizontal sectlon and a front elevation of a bucket.

Referring to the a paratus illustrated, the p the inlet valve A and discharges through the outlet B, striking the water wheel, which I designate as a whole by the letter C, tangentially and rotating it, the rotation being transmitted through a pinion D to any suitable mechanism.

The wheel 0 is formed of a central plate E to which are attached the buckets F. Various forms of wheels have been heretofore'used, the prevailing one consisting of a central spider with buckets soldered thereon. Besides the minor disadvantages of the obstruction to rotation in the water which always surrounds the wheel and which obstruction is due to the spider and to the comparative clumsiness of the soldered joints, there was a serious expense involved, and difficulty in preserving the perfect balance of the wheel.

By the present invention the buckets may be made very cheaply, of the shape which is theoretically most efficient, and are fastened very neatly and chea ly to a solid disk which does not churn t e water in which it is embedded as would a spider, and whose rotation therefore is not resisted to the same extent as would be the rotation of a spider.

The disk E is provided with a number of slots G extending in the ease illustrated in a tangential direction, and each bucket. is fastened by having a portion passed through a slot G, bent down over the solid portion of the plate at top and bottom, and riveted through the bent-over portion. The buckets shown are spherically shaped, each constituting something less than a hemisphere, and are stamped out in such a form as to provide a tangential portion H from the bottom of the bucket portion J, and to provide flanges K overlapping the plate and through which the attaching rivet L fastens. It will be understood that the space between the upper and lower flanges K is substantially or largely filled by the portion of the plate E which lies between two adjacent slots the edge of the plate being formed with concave portions approximately fitting the concavities of the buckets, (see Fig. 2).

In Fig. 3 it is apparent that the flanges K and the intermediate portion H of the fasteningmembers of the buckets are tapered on the inner side of the bend so as to fit the chamfered edges M of the slot in the plate E. This prevents the inverting of the buck ets, insuring that the opening of each bucket shall be at the correct side. The con struction described has also an advantage in permitting the casing to be formed with an annular depression N adjacent to the depending parts of the buckets so as to minimize the quantity of water carried in the meter and carried around with the rotating wheel, while at the same time reservin the necessary clearance around al parts of the rotating wheel.

What I claim is l. A water wheel having a thin central member and wide buckets, said central memher having slots in its edge and said buckets having narrow inward extensions enterin said slots and flanges at the sides of sai narrow extensions fastened upon the face of said central member to hold the bucket in position; each of said buckets with said extension and flanges being formed integrally of sheet meta and having tangential] portions H extending from the bottoms of the buckets and flanges K overlapping said member, said member having slots into which said portions H of the buckets enter.

3. A \vaternvhcel having a central mem her, and concave buckets having flanges overlapping said member, the edge of the central member being formed with concave portions approximately fitting the coneavi- 1e ties of the buckets.

In witness whereof, I have hereunto signed my name in the presence of two subscribing witnesses.
